God already knows what we're made of, but perhaps He wants us to learn what we're made of. I think we would all agree that we learn more from our tough times than from our easy times.
Power corrupts the few, while weakness corrupts the many. The resentment of the weak does not spring from any injustice done to them but from the sense of their inadequacy and impotence. They hate not wickedness but weakness. When it is in their power to do so, the weak destroy weakness wherever they see it.
The remarkable thing is that we really love our neighbor as ourselves: we do unto others as we do unto ourselves. We hate others when we hate ourselves. We are tolerant toward others when we tolerate ourselves. We forgive others when we forgive ourselves. We are prone to sacrifice others when we are ready to sacrifice ourselves.
